I'm only going to explain this once because this topic, as well as most online topics, is more about emotions than facts. But here we are.

You didn't understand how this helps because you aren't trained to think like a child predator. (That's fine.) I've had to take a lot of child safety trainings over the years for professional reasons. Here's how online child predators work, they start by trying to get the kid into a secret. They say "hey want to see some porn?", and of course the kid is curious. And the kid is told, "be sure you don't tell your parents about this." Then they slowly try to pull into deeper and deeper secrets and start to black mail the kid. They start to demand that the kid send them nude photos. They trap the kids into deeper and deeper secrets and guilt to get more and more out of them. In the worst cases this results in meetups with the predator in person.

The easiest places for the predators to start this process is porn sites where the kids are visiting in secret to begin with. Those are the kids that are most vulnerable.

How how did this protect kids? The goal is to keep the kids out of spaces where they would be targeted to begin with.

So there you go. I'm all ears for how to do this better.
